5 top tips for finding a trustworthy car mechanic

Use search engines to check that they have a website, customer reviews or at least proof of company history. You’ll get a good idea of their legitimacy, reputation and trustworthiness. A good tip would be to type in the name of the garage along with a keyword like “complaints”.

If a car mechanic is to be trusted, their accreditations and quality standards shouldn’t be hard to find. Garages need certain accreditations to operate in the UK, and their certificates should be displayed in plain sight for customers to see clearly.

When you ask a mechanic or service centre to quote - make sure you get it in writing! Not only will this help you compare the quote with other fitters but it will also make sure you’re not hit with hidden bills or unjustified parts and add on’s.

It’s important to find a car repair garage that speaks your language. You’ll want to know exactly the repairs you’re paying for and why - and jargon could be a distraction to skirt over hidden costs.

Don’t hesitate to ask your mechanic for a demonstration both pre and post-repair. This way you not only have proof that a repair is needed but also have a visible comparison that it was resolved to an honest standard.
